Consider the following situation. Sonia is traveling to Mexico. Answer the following questions about her trip. a. Sonia starts with \$100 in cash and changes it into pesos at a rate of 1 peso \$0.075. Which of the following would be a correct way to use dimensional analysis to make this conversion? $\frac{1}{\$100} \quad \frac{1 \text{ peso}}{\$0.075}$ $\$100 \quad \frac{1}{\$0.0750}$ $\frac{1}{\$100} \quad \frac{\$0.075}{1 \text{ peso}}$ $\$100 \quad \frac{1 \text{ peso}}{\$0.0750}$ b. Sonia spends 955 pesos while in Mexico. She converts her remaining pesos back into dollars. How many dollars does she have? Round to the nearest dollar. c. While traveling in Mexico, Sonia wanted to be able to estimate how much things cost in dollars. Explain a strategy that could be used to estimate the conversion.
